In the daily use process, the oil press machine can press a lot of oil, such as peanuts, rapeseed, oil sunflower, flax seeds, pepper seeds, etc. Today, I will briefly describe the pressing process of rapeseed and peanuts.
The method of pressing rapeseed: the rapeseed is divided into cold pressing and hot pressing. In order to improve the oil yield and the quality of the oil, it is generally hot pressed. The process is as follows: 1. Cold pressing: screening - rolling embryo - pressing - hot pressing: screening - rolling embryo - steaming - pressing cold pressing: first screening the rapeseed to remove impurities, then check Rapeseed water content. No test equipment can be tested by soil method: squeeze the rapeseed with nails, if there is noise, and divide into two pieces, or oil extrusion is optimal, if it is powder, it is too dry. If it is a cake, it is too wet. If it is too dry, add 2.5%~3% water, stop it less, and directly enter the oil press for pressing. Generally press twice. Hot squeeze: put the rapeseed into
Screening and removing impurities, then entering the embryos of the compactor, rolling the embryos and then entering the steaming wok for steaming. In the process of frying the seeds, 2%~3% water is added in the domestic, until the seeds are brownish yellow, the temperature is 110~ 120 degrees is the most suitable before it can be squeezed.
Peanut kernel crushing method: peanut kernel hot pressed and cold pressed can be, most people now mainly hot press. The cold press effect is not as hot as hot press. When hot pressing, the peanut kernels are first crushed or rolled, and then steamed in a steamer for 1.5 to 2 hours. The temperature is about 120 degrees, and the water content is about 3%, which can be pressed into the press. When the temperature of the oil press reaches 85 degrees, it starts. Normal press. If there is no steamer, you can also put the peanut kernels in a wok. First crush the peanut kernels, gradually add about 7% to 8% of water, stir fry until dark yellow, you can squeeze out the pot.
